We're dividing 90219454 by 186 
The aim is to understand the frequency of 186 in 90219454.

On to step 1:
The number 186 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 186

Step 2:
186 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 186

Advancing to step 3:
902 divided by 186 is 4 with a remainder of 158.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 744 from 902 and we're left with 158.
Grab the next digit (1) from the dividend, add it to 158, then carry on: 1581 / 186

On to step 4:
186 can be fit into 1581 8 times, resulting in a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 93 after subtracting 1488 from 1581.
Include the next digit (9) from the dividend after 93, then repeat: 939 / 186

Step 5:
The number 186 fits into 939 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 485.0
Deduct 930 from 939 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 186

Going ahead to step 6:
186 can be fit into 94 0 times, resulting in a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 4850.0
Subtracting 0 from 94 leaves us with 94.
Bring next digit (5) of the dividend behind the 94 and repeat the process: 945 / 186

Step 7:
945 divided by 186 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 48505.0
Subtract 930 from 945 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 186

Step 8:
154 divided by 186 is 0 with a remainder of 154.
Write down 0 as next digit of the result. 
Result so far: 485050.0
Subtract 0 from 154 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 9:
If we divide 1540 by 186, we get 8 and a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 485050.8
If we subtract 1488 from 1540, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
186 goes into 520 2 times with a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 485050.82
If we subtract 372 from 520, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 11:
When dividing 1480 by 186, we get 7 with a remainder of 178.
Put 7 as the next digit of the answer. 
Result so far: 485050.827
Subtract 1302 from 1480 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 12:
1780 divided by 186 is 9 with a remainder of 106.
Use 9 as the next digit of our solution. 
Result so far: 485050.8279
Deduct 1674 from 1780 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 13:
When dividing 1060 by 186, we get 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 485050.82795
Subtract 930 from 1060 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 14:
186 goes into 1300 6 times with a remainder of 184.
Use 6 as the next digit of our solution. 
Result so far: 485050.827956
The remainder is 184 after subtracting 1116 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 15:
The number 186 fits into 1840 9 times, leaving a remainder of 166.
The number 9 becomes the next digit in our result. 
Result so far: 485050.8279569
If we take 1674 away from 1840, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 16:
1660 divided by 186 is 8 with a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 485050.82795698
Deduct 1488 from 1660 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 485050.82795698, and the remainder is 1.72e-07.
